SBS 2008 DNS stops working for .uk, .eu and some other TLDs outside USA

Filed under: SBS 2008 — Rahul Patel @ 1:45 pm

In SBS 2008, when first installed or rebooted, DNS queries succeed, but after a period of about 1 day users report that they are unable to access some web sites. On inspection, it may be noticed that the inaccessible web sites are in the .uk and .eu Top Level Domains (TLDs) or certain other TLDs that are outside of the USA.

If left for several days, the problem may appear to resolve itself then re-occur after another day or so.

If the DNS server service is restarted, or the DNS cache on the server is cleared, then the problem is temporarily resolved but re-occurs after a day or so.

The cause of this problem is that in EU countries (and certain other TLDs outside the USA), nameserver records are typically cached for more than 1 day. SBS2008 has a cap on the maximum time that it will allow nameserver records to be cached, which defaults to 1 day. This default works fine in the USA but When the .uk and .eu records become stale, they are not deleted from the cache but are no longer returned as valid records. Therefore, they effectively prevent DNS lookups in those TLDs from succeeding until the records expire and are deleted from teh cache, or the DNS Server service is restarted.

The fix is to increase the maximum Time To Live (TTL) setting in the DNS server so that it recognises records older than 1 day. Experience has shown that setting the value to 4 days is usually enough, but the maximum setting is 30 days.

Solution

For a permanent work around, the MaxCacheTTL value needs to be changed to a value larger than the TLD TTL (Default value is 1 day, maximum value is 30 days). On SBS2008 there is no negative impact since this is the TTL for the cache of Resource Records. This is just the maximum value that it will be stored on DNS server. If the actual TTL is shorter, the shorter value will be used.

1. Start Registry Editor (Regedit.exe).
2. Locate the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters
3.On the Edit menu, click New, click DWORD (32-bit) Value , and then add the following value:

Value: MaxCacheTTL
Data Type: DWORD
Data value: 0x69780 (432000 in decimal = 5 days)

4.Click OK .
5. Quit Registry Editor.
6. Restart the DNS server.

Create bootable USB drive for Hyper-V Server 2008 R2

Filed under: Hyper-V,Server 2008 — Rahul Patel @ 9:59 am

BootFromUSB is a simple application to automate the manual preparation process for booting Hyper-V Server 2008 R2 off of USB drives.

Description
A simple application to automate the preparation process for booting Hyper-V Server 2008 R2 off of USB drives.

The application automates the manual USB creation process detailed on the Microsoft website.

Requirements

* Copy the EXE locally
* You have the Windows AIK or Windows OPK installed.
* You are running as a local admin
* You have the INSTALL.WIM file for Hyper-v Server 2008 R2 available.
* You have .NET 3.5 or later installed.
BootFromUSB-screenshot.PNG

Directly using a prepped Hyper-V Server 2008 R2 VHD file (instead of from a WIM):

One additional feature of BootFromUSB is you can leave the WIM field (step3) blank and
select a “Blank” VHD that is actually a pre-configured sysprepped VHD and it will directly
copy the VHD to the USB drive.

This is a quick way to prep USB drives since it skips the long VHD creation and WIM
extraction processes.

NOTE: The operating system will display a “Format disk?” dialog box a number of times while preparing the USB drive. You should ignore and just close those dialogs.

2.Microsoft Office Live Communications Server
3.Microsoft Systems Management Server (SMS)
4.Microsoft Office Outlook
5.Microsoft Operations Manager (MOM)
6.Windows SharePoint Services

8.Active Directory Certificate Services (AD CS)
9.Active Directory Rights Management Services (AD RMS)
10.Credential Roaming
11.Distributed File System (DFS)
12.Distributed File System Replication (DFSR) and File Replication Service (FRS)
13.Domain Name System (DNS)
14.Dynamic Host Configuration Protocol (DHCP)
15.Group Policy
16.Internet Authentication Service
17.Internet Information Services (IIS)
18.Network Access Protection (NAP)
19.Terminal Services (Users and Computers snap-in)
20.Terminal Services Licensing server

Note:Exchange isn’t on the list. In fact, you can’t run Exchange (2000, 2003, 2007) if there’s only a RODC it can connect to. Exchange needs a full-DC around to function correctly.

Disk2vhd v1.0

Filed under: Hyper-V,Server 2008 — Rahul Patel @ 10:28 am

Sysinternals  offers a free P2V tool Called Disk2VHD that creates VHDs (Virtual Hard Disks) of physical disks for use in Microsoft Virtual PC and/or Hyper-V virtual machines (VMs).  You can run Disk2vhd on a system that’s online, since it uses Windows Volume Snapshot (VSS) capability, to create consistent point-in-time snapshots of the volumes you want to include.

To use VHDs produced by Disk2vhd, create a VM with the desired characteristics and add the VHDs to the VM configuration as IDE disk(s).
On first boot, a VM booting a captured copy of Windows will detect the VM’s hardware and automatically install drivers, if present in the image. If the required drivers are not present, install them via the Virtual PC or Hyper-V integration components.

You can also attach to VHDs using the Windows 7 or Windows Server 2008 R2 Disk Management or Diskpart utilities.
